digitalultrasonicinspection

EPJF-D Partial discharge detector is a new type of digital partial discharge detector. It is suitable for partial discharge live inspection of high-voltage electrical equipment such as transformers, GIS, switch cabinets, cables, arresters, and transformers. The partial discharge detector is equipped with different sensors to collect signals, and then detect and evaluate the operation status of high-voltage electrical equipment, avoid sudden accidents of equipment, and effectively detect equipment insulation deterioration, breakdown, flashover and other serious phenomena. The whole set of equipment adopts ultrasonic detection technology, high frequency detection technology, signal field processing technology, Web background processing software and other technologies for detection and analysis. At the same time, the high-speed AD conversion circuit is used to complete the digitization of the signal, and the reliability of the detected data is ensured by digital signal processing, adaptive filtering and other interference signal processing methods. Using this equipment to conduct partial discharge live inspection on high-voltage electrical equipment, it is convenient for staff to evaluate the operating status of high-voltage electrical equipment in time, which provides a basis for equipment maintenance, and can also track and test the fault points of operating equipment, which greatly improves the performance of the equipment. Reliability, safety and effectiveness of the operation of high-voltage electrical equipment.
